Conversion Rails

Yes, when converting your crib to a full-size bed with these 75-inch rails, a box spring or a Bunkie board is typically required to support the mattress. Because the rails provide the length and side structure, a secondary support system (foundation) is necessary to ensure the mattress stays level and provides the firm support needed for a growing child’s spine.

Based on our expertise in the furniture lifecycle, we highly recommend purchasing conversion rails at the same time you buy the crib. Furniture collections and finishes can be updated or retired over several years; securing the rails now ensures you will have a perfect color match and a guaranteed fit when your child is ready to transition, avoiding the common frustration of trying to find discontinued parts later.

To ensure maximum safety and structural integrity, these conversion rails are engineered to fit specific Rooms to Go crib models. Using brand-specific rails is essential for a precise fit, as it eliminates dangerous gaps between the mattress and the frame that could occur with "universal" kits. We recommend matching the SKU or collection name of your crib to ensure these rails are the correct compatible component.

Transitioning to a full-size bed is a significant lifestyle change that requires more floor space than the original crib. With a depth of 75 inches and a width of 56 inches, this bed will have the footprint of a standard adult bed. For families in urban apartments or smaller suburban bedrooms, we suggest measuring your space to ensure there is still adequate room for a dresser or play area once the full-size conversion is complete.

While a toddler guard rail is a short, partial rail used to prevent a child from rolling out of a converted daybed, these conversion rails are full-length (75 inches) components designed to transform a crib into a standard full-size bed. These rails replace the crib’s side panels and connect the headboard and footboard to accommodate a 54" x 75" full mattress, effectively extending the furniture's use from infancy through the teenage years.

These conversion rails are built for long-term durability, designed to support the weight and movement of an older child or teenager. Once properly assembled and connected to the headboard and footboard, they create a rigid, stable frame. For very active sleepers who are just transitioning from a crib, you may still choose to use an additional mesh safety rail until they become accustomed to the height and size of a full bed.
